The atBOS sensor network comprehensively monitors a building’s indoor environment and energy use. The data facilitates building management and can also be used in various independently assessed certifications relevant to its environmental, social and corporate governance (ESG) rating. This article introduces the main residential and non-residential certifications used in Britain.
Cutting domestic carbon emissions is essential to achieving net-zero by 2050. Current policy is to renovate existing buildings to energy performance certificate (EPC) band C. However, that does not measure carbon emissions so every building could achieve band C and still leave the sector far short of net-zero. Here’s why.

In this article we look at the impact of psi-values and why they matter. Psi-values are a measure of the heat loss of a junction between two fabric elements, eg floor and external wall. These junctions are called non-repeating thermal bridges.
Previous iterations of the UK Building Regulations have raised awareness of the importance of fabric u-values and air tightness, the incoming revision is set to sharpen the focus on the ‘non-repeating’ or ‘linear’ thermal bridges that occur at junctions between fabric elements. The easy option of using Accredited Construction Details (ACD) will disappear from SAP as a new version is introduced next summer. This will force developers to more strongly consider junctions when choosing their building fabric or to have the heat loss properties of their junctions evaluated by trained specialists in order to avoid having to assume worst-case default heat losses.
